V Precautions must be observed when using high frequency devices. Use the spe-
cial high frequency ESAOTE patient cable to avoid possible signal interference
during ECG acquisition.
V There is no danger when using the ECG unit simultaneously with electrical stimu-
lation equipment. However, the stimulation units should only be used at a sufficient distance from the electrodes. If in doubt, the patient should be disconnected
from the monitor.
V If the patient cable should become defective after defibrillation, an electrode be-
comes displaced, or an electrode resistance is too high, a lead-off indication is
displayed in the upper right part of the screen and an acoustic alarm given.
1.7 Maintenance

Resting ECG 4
User Guide Electrode Placement 4.1
A minimal resistance between skin and electrode is required to obtain the best ECG
signal and ensure the highest quality ECG recording. Therefore please note the following points:
1. Ensure that the patient is warm and relaxed.
2. Shave electrode area before cleaning.
3. Thoroughly clean the area with alcohol.
4. When applying the electrodes, ensure that a layer of gel is between the electrode
and the skin.
5. Place the C4 electrode first - in the 5th intercostal space (ICS) so that it lines up
approximately with the middle of the clavicle.
6. Then place:
– C1 in the 4th ICS parasternal right
– C2 in the 4th ICS parasternal left
– C3 between, and equidistant to, C4 and C2
– C6 on the patient‘s side and aligned with C4
– C5 between, and equidistant to, C4 and C6
The electrode resistance can be checked in the recording screen - see paragraph
4.3.1.
When making an ECG with a child it is sometimes physically difficult to place all
electrodes. When this is the case electrode C4 can be placed on the right side of the
chest.
V During the ECG recording, ensure that neither the patient nor the leading parts of
the patient connection nor the electrodes (including the neutral electrodes) come
in contact with other persons or conductive objects, even when these are earthed.

4.2.1 Nehb Leads
The Nehb leads are bipolar chest leads. They are of special interest for the diagnosis
of changes in the posterior ventricle wall. Three leads are arranged in the form of a
triangle, also called the “small cardiac triangle”. Nehb dorsal (D) is measured between
the electrode positions Nax and Nst; Nehb anterior (A) between Nap and Nst, and
Nehb inferior (J) between Nap and Nax.
Place the electrodes as follows:
Colour Code Electrode identifier Applied to position
Red C1 (Nst) 2nd rib at the right sternal border
Yellow C2 (Nax) directly opposite (on the back, posteriorly)
from 3 (Nap)
Green C3 (Nap) 5th intercostal space medioclavicular line (car-
diac apex)
All other electrodes can be placed in their normal position The user defined lead order
must be set in the Setup menu:

• With patient connected (good connection, low resistance): ± 100mV
An offset of up to ±300mV will give an acceptable recording.
• With patient simulator connected: ±20 mV
This will depend on the patient simulator used and must be taken as a flexible measurement.
• With all electrodes shorted together: ±20 mV
• No patient cable connected: -350 to -500mV

V When non-medical devices are connected to the RS-232 interface ensure that
both units are securely connected to the same earth potential.
V When operating the unit on battery and simultaneously using non-medical devi-
ces, the RS-232 interface must be fully isolated.
V An external device must only be connected using the original interface cable as-
sembly.
The contents of the memory can be transmitted to the ArchiMed data management
program, using the RS-232 connected directly to the computer, or over the telephone
system. Sending directly is termed LINE transmission; sending over the telephone system requires a modem and this form of sending is termed MODEM.
When Transmit is selected, the message ‘TRANSMITTING‘ appears in the message
box, during the transmission.
Line Transmission To transmit recordings over line, proceed as follows:
1. Set Communication mode to LINE - see page 40
2. Connect the cable assembly (optional accessory, art. No. 8830649000) between
the RS-232 connector on the P8000 plus and the COM interface of the Computer.
3. Ensure that the ArchiMed SW communication program is active on the computer
(see ArchiMed SW handbook).
4. Press the TRANSMIT softkey.
Modem Transmission To transmit recordings over the telephone network, proceed as follows:
1. Set Communication mode to MODEM - see page 40
2. Enter Phone number and modem initialisation codes - see page 40
3. Connect the modem cable assembly (supplied with modem) between the RS-232
connector on the P8000 and the modem.
4. Ensure that the ArchiMed SW communication program is active on the remote
computer (see ArchiMed SW handbook).
5. Press the TRANSMIT softkey
The message TRANSMITTING appears while the unit is sending
If a transmission error occurs the message Tx ERROR is displayed.
« Check all settings in the ArchiMed SW communication program

6 Care & Maintenance
Maintenance work not described in this chapter, e.g. battery changes, may only be
accomplished by a qualified technician.
Self-test
Every time the unit is switched on a built-in test program is initiated. If an error is detected, the unit will not switch on and a table may be displayed giving information for
the service staff. Details of the test program is given in the P8000 Service Handbook.
6.1 Communication (RS-232) Test
A built-in program to check the transmission connector. This test is entered from the
‘setup‘ menu:
SETUP > SYSTEM SETTINGS > TEST AND INFO > COMM TEST
This test uses a special test plug (not supplied) which shorts the incoming/outgoing
connectors to check transmission line and connector to ensure that the P8000 transmission circuits are functioning. Details of this test are given in the P8000 Service
Handbook.
6.2 12 Monthly Check
It is stipulated that a technical safety check must be performed at least every 24 months. It is strongly recommended however, that the unit undergoes a technical safety
check every 12 months.This safety check shall include the following:
• Visual inspection of the unit and cables.
• Electrical safety tests according to EN 60601-1 (1990) Clause 19
• Functional tests according to the Service Handbook.

6.5 Cleaning
6.5.1 Cleaning the Casing
V Switch the unit off before cleaning and disconnect the mains. Do not, under any
circumstances, immerse the apparatus into a cleaning liquid or sterilise with hot
water, steam, or air.
The casing of the P8000 can be cleaned with a soft damp cloth on the surface only.
Where necessary a domestic non-caustic cleaner can be used for grease and finger
marks.
6.5.2 Cleaning the Patient Cable
The patient cable must not be exposed to excessive mechanical stress. Whenever disconnecting the leads, hold the plugs and not the cables. Store the leads in such a
way as to prevent anyone stumbling over them or any damage being caused by the
wheels of instrument trolleys.
The cable can be wiped with soapy water. Sterilization, if required, should be done
with gas only and not with steam. To disinfect, wipe the cable with hospital standard
disinfectant.
6.5.3 Cleaning the Thermal Print Head
If the printer is used a lot, a residue of ink from the grid on the paper can build up on
the print head. This can cause the print quality to deteriorate. We recommend therefore that every month the print head is cleaned with alcohol as follows:
Extend the paper tray and remove paper. The thermal printhead is found under the
paper tray.
With a tissue dampened in alcohol, gently rub the printhead to remove the ink residue.
If the printhead is badly soiled, the colour of the paper grid ink (i.e. red or green) will
show on the tissue.

6.6 Replacing the Recording Paper
The recording paper must be replaced as soon as the end of the paper is indicated
by a red stripe on the lower edge. After the indication first appears, there are about 8
pages left. However, we recommend that the paper be replaced immediately. If no paper is left, the printing process is interrupted and a warning is given on the screen. To
replace the paper proceed as follows:
1. Press the locking catch (1) to the right. Open the printer door opens upward.

2. Remove any remaining paper from the paper tray.
3. Place the beginning of the paper over the black paper roller.
4. Close the cover. Be sure that the paper lies exactly between the rails.
5. Press the STOP key to transport the paper to the start position.
ESAOTE can only guarantee perfect printouts when ESAOTE original chart paper or
chart paper of the same quality is used.
6.6.1 Thermal Paper Handling
The thermal paper used in the P8000 requires slightly different handling to normal paper as it can react with chemicals and to heat. However, when the following points are
remembered, the paper will give reliable results:
The following points apply to both storage, and when archiving the results.
1. Before use, keep the paper in its original cardboard cover. Do not remove the cardboard cover until the paper is to be used.
2. Store in a cool, dark and dry area.
3. Do not store near chemicals e.g. sterilisation liquids.
Art.-no.: 9740440041 Rev.: a
4. In particular do not store in a plastic cover.
5. Certain glues can react with the paper - do not attach the printout onto a mounting
sheet with glue.
